The process to get the info involves the nurse and some time passing.
The reason being that the display of it requires the basic sub dermal implant to be upgraded to the medical version.
- The medical upgrade is done by
- Talking to the nurse
- After the 15 day
- With enough charm/affection.
If those are fulfilled simply select the nurse and the sub dermal implant option.
This will make her upgrade it.
Game variables (tinkering not suggested)
- Shift + 0 for console
- player.monitoring_sub_dermal
- The value needs to be 2 or higher for the info to be shown
Have tested on a new start and old save, both works.
